API / Belt / HashSetString

You are currently looking at the v6.0 - v8.2 docs (Reason v3.6 syntax edition). You can find the latest API docs here.

(These docs cover all versions between v3 to v8 and are equivalent to the old BuckleScript docs before the rebrand)

HashSetString

This module is Belt.HashSet specialized with key type to be a primitive type.

It is more efficient in general, the API is the same with Belt.HashSet except its key type is fixed, and identity is not needed(using the built-in one).
